ABSTRACT:
While weaving fabrics (501, 502, 601, 602) on a weaving machine, in successive weft insertion cycles two weft yarns (505, 506, 605, 606) are simultaneously inserted at different weft insertion levels between pile warp yarns (520, 530, 620, 630) which are positioned with respect to the weft insertion levels by a three-position-non-open-shed Jacquard machine. The Jacquard machine is provided to maintain one or several pile warp yarns (503, 504, 603, 604) in successive operating cycles of the weaving machine in an upper and/or a lower position. The pile warp yarns (503, 504, 603, 604) in their upper or in their lower position are positioned between the weft insertion levels. Furthermore, a three-position-non-open-shed Jacquard machine and a weaving machine are provided to carry out such a method, and a method to rearrange the harness suspension of a three-position-non-open-shed Jacquard machine.
